Implementations

impl CaseMapper

pub fn create() -> Box<CaseMapper>

Construct a new CaseMapper instance using compiled data.

pub fn create_with_provider( provider: &DataProvider, ) -> Result<Box<CaseMapper>, DataError>

Construct a new CaseMapper instance using a particular data source.

pub fn lowercase(&self, s: &str, locale: &Locale, write: &mut DiplomatWrite)

Returns the full lowercase mapping of the given string

pub fn uppercase(&self, s: &str, locale: &Locale, write: &mut DiplomatWrite)

Returns the full uppercase mapping of the given string

pub fn titlecase_segment_with_only_case_data_v1( &self, s: &str, locale: &Locale, options: TitlecaseOptionsV1, write: &mut DiplomatWrite, )

Returns the full titlecase mapping of the given string, performing head adjustment without loading additional data. (if head adjustment is enabled in the options)

The v1 refers to the version of the options struct, which may change as we add more options

pub fn fold(&self, s: &str, write: &mut DiplomatWrite)

Case-folds the characters in the given string

pub fn fold_turkic(&self, s: &str, write: &mut DiplomatWrite)

Case-folds the characters in the given string using Turkic (T) mappings for dotted/dotless I.

pub fn add_case_closure_to( &self, c: DiplomatChar, builder: &mut CodePointSetBuilder, )

Adds all simple case mappings and the full case folding for c to builder. Also adds special case closure mappings.

In other words, this adds all characters that this casemaps to, as well as all characters that may casemap to this one.

Note that since CodePointSetBuilder does not contain strings, this will ignore string mappings.

Identical to the similarly named method on CaseMapCloser, use that if you plan on using string case closure mappings too.

pub fn simple_lowercase(&self, ch: DiplomatChar) -> DiplomatChar

Returns the simple lowercase mapping of the given character.

This function only implements simple and common mappings. Full mappings, which can map one char to a string, are not included. For full mappings, use CaseMapper::lowercase.

pub fn simple_uppercase(&self, ch: DiplomatChar) -> DiplomatChar

Returns the simple uppercase mapping of the given character.

This function only implements simple and common mappings. Full mappings, which can map one char to a string, are not included. For full mappings, use CaseMapper::uppercase.

pub fn simple_titlecase(&self, ch: DiplomatChar) -> DiplomatChar

Returns the simple titlecase mapping of the given character.

This function only implements simple and common mappings. Full mappings, which can map one char to a string, are not included. For full mappings, use CaseMapper::titlecase_segment.

pub fn simple_fold(&self, ch: DiplomatChar) -> DiplomatChar

Returns the simple casefolding of the given character.

This function only implements simple folding. For full folding, use CaseMapper::fold.

pub fn simple_fold_turkic(&self, ch: DiplomatChar) -> DiplomatChar

Returns the simple casefolding of the given character in the Turkic locale

This function only implements simple folding. For full folding, use CaseMapper::fold_turkic.
